Excel has two very useful functions when it comes to generating random numbers. RAND and RANDBETWEEN.
Rand
The RAND function generates a random decimal number between 0 and 1.
1. Select cell A1.
2. Type RAND() and press Enter. The RAND function takes no arguments.
Note that cell A1 has changed. That is because random numbers change every time a cell on the sheet is calculated.
4. If you don’t want this, simply copy the random numbers and paste them as values.
5. Select cell C1 and look at the formula bar. This cell holds a value now and not the RAND function.
RandBetween
The RANDBETWEEN function generates a random whole number between two boundaries.
1. Select cell A1.
2. Type RANDBETWEEN(50,75) and press Enter.
3. If you want to generate random decimal numbers between 50 and 75, modify the RAND function as follows:
RandArray
If you have Excel 365, you can use the magic RANDARRAY function.
1. By default, the RANDARRAY function generates random decimal numbers between 0 and 1. The array below consists of 5 rows and 2 columns.
Note: this dynamic array function, entered into cell A1, fills multiple cells. Wow! This behavior in Excel 365 is called spilling.
2. The RANDARRAY function below generates an array of integers, 10 rows by 1 column, between 20 and 80.
Note: the Boolean TRUE (fifth argument) tells the RANDARRAY function to return an array of integers. Use FALSE to return an array of decimal numbers between 20 and 80.

How to generate random value from a given list in Excel?
To generate random number is easily done by the function =RANDBETWEEN(range), but have you ever tried to generate random value from a given list as below screenshot shown?
Generate random value from a given list by formula
Generate random value from a given list by formula
Actually, there are some easy formulas that can help you to quickly generate random value from a given list.
Select a blank cell that will place the random value, type this formula =INDEX($A$2:$A$16, RANDBETWEEN(2, 16)), then press Enter key. See screenshot:
In the formula, A2:A16 is the given list you want to use, 2 and 16 are the starting row number and ending row number of the list.
If you want to generate several random values from the list, you can drag the formula down as you need. See screenshot:
You can press F9 key to refresh the values.
Note: If you want to generate random number based on a list, you can use this formula =INDEX($I$2:$I$7, RANDBETWEEN(1, 6)), and press Enter key.

How To Randomly Sort A List In Excel
Have you ever needed to take a list and randomly sort it? How would you do it? It’s not as intuitive as you think. We’re so used to sorting lists in alphabetical order or from smallest to largest, but this idea of randomly sorting a list is not very common in Excel. Let’s jump right into it and show you how to randomly sort a list in Excel.
Sample Data
Say we have some data that we’d like to sort:
Normally, we could sort by Movie title, the date that it opened (as it’s shown in the picture), or by the total amount it grossed. But what if we wanted to “shuffle” this list? How could we go about doing that?
By the way, this is the same data that we used in the Sum the Top 5 Values post.
You can also copy and paste this table to follow along:
Movie Date Opened Total Gross
Deadpool 2/12/16 $363,070,709
Zootopia 3/4/16 $341,268,248
Batman v Superman: Dawn of Justice 3/25/16 $330,360,194
The Jungle Book (2016) 4/15/16 $364,001,123
Captain America: Civil War 5/6/16 $408,084,349
Finding Dory 6/17/16 $486,295,561
The Secret Life of Pets 7/8/16 $368,384,330
Suicide Squad 8/5/16 $325,100,054
Rogue One: A Star Wars Story 12/16/16 $532,177,324
Sing 12/21/16 $270,329,045

Randomly Sort a List in Excel
To sort a list randomly in Excel, first you need to add a new column to your data. When using Excel Tables, you can simply type in a new column name at the next available table header and it will be automatically joined to your table.
Here, we type in “Sort Order” and press Enter.
Next, we need a way to randomly sort the list. We can use the RAND() function in Excel to help us with that. The RAND() function will return a number at random between 0 and 1.
After we add the formula, we can sort by that column. This will randomize the list for us.
Also, each time the RAND() function is calculated, you get a different number. This is why you see the table has all different numbers.
Keep Shuffling
Another cool tip is that if you’re not happy with the initial shuffling of the list, you can simply keep sorting between Ascending and Descending to keep shuffling the list. This works because when you sort the list, it recalculates the RAND() function, giving a new number each time.
Keeping the List Order
But what if you don’t want the RAND() function to keep recalculating? What if you want to keep the sort order?
If you want to keep the sort order, you can simply save the values from RAND() before sorting again.
